Plumbing in Washington splits between water that will not leave and water that freezes. West of the Cascades a deep freeze is less common and still not impossible, and the ordinary trouble is drainage. Saturated soil, a slow side sewer, and downspouts that drown a foundation drain show up all wet season. Older streets may still have galvanized supply and clay laterals that have shifted. East of the Cascades a hard freeze will split a hose bib, an uninsulated line, or a pipe in a crawl space left open to the wind.
Describe the symptom without a speech. No hot water, a wet ceiling, a toilet that gurgles when the laundry drains, a sewer smell, or a bib that weeps only after a cold night. Say whether you are on a public main or a well. Plenty of houses off the main towns are not on a city supply, and a pressure problem at a well is not a street-main problem. A sump that runs all through the wet season is a different call from a water heater that has quit.
Know where the main shutoff is, and say if you cannot find it. A leak call should include where the water heater sits, in a garage, a closet, or a crawl, and whether the pan has already rusted through. On the wet side, ask yourself if the water is coming from a drain or seeping in from the soil. On the cold side, name the exterior walls and the unheated spaces the pipes cross. Those details decide the next hour.
If water is spreading now, shut off what you safely can and call with the town and the floor where it shows. If this ties to a claim, say whether the break looks sudden, and have your deductible in mind. A slow seep and a burst line are not the same story, and groundwater is not the same story as either of them.
The wet season or the next hard night will test the joint you are ignoring. Call with the town and one sentence: leak, clog, freeze, or no hot water. Call the number on this page.
